Critical security and vulnerability fixes will be provided according to the following terms and conditions:

• Cisco TAC will first use commercially reasonable efforts to work with the customer to determine the locality of impact and to find a workaround for the problem.

• If an alternative workaround is not possible during the extended period of support, then Cisco will make commercially reasonable efforts to provide a "bug fix" solution in Release 12.0(32)S or in a later supported software release to remedy the problem.

• If despite commercially reasonable efforts Cisco is unable to provide a software-based solution, it may be necessary for the customer to remove or upgrade the affected software-based systems to correct the problem.

15-March-2010

Engineering software support provided only through rebuilds of Release 12.0(32)S or later

Last date of support

The last date to receive Cisco TAC service and support for the product. After this date, all support services for the product are unavailable, and the product becomes obsolete.

The listed Cisco IOS Software Release versions are a representation of Release 12.0(2)S through Release 12.0(31)S releases. Additional maintenance rebuilds of Release 12.0(2)S through Release 12.0(31)S -- for example, 12.0(31)Sx, where "x" indicates the next maintenance rebuild -- may occur prior to the end of software maintenance. All components of Release 12.0(2)S through Release 12.0(31)S, including rebuilds and corresponding images of releases, are included in this end-of-sale/end-of-life announcement.

Product Migration Options

Cisco recommends that customers regularly take inventory of the Cisco IOS Software releases deployed in their networks. This helps to ensure that networks run the most currently supported releases available from Cisco. In general, the migration path for a Cisco IOS Software release is to the latest version of that release. The latest version incorporates the current software fixes, hardware support, and new software features.

Customers using any release of the Cisco IOS Software from Release 12.0(2)S through Release 12.0(31)S on current Cisco IOS Software-maintained hardware are encouraged to migrate to Release 12.0(32)S or later, which inherits all functionality and software fixes from previous Cisco IOS Software Releases 12.0 S, includes additional functionality and software fixes, and receives extensive integrity testing for added quality.

Note: When upgrading to a more recent release, certain software images may not be available, hardware may or may not be supported, and memory requirements may have changed. Always consult the Cisco IOS Software Upgrade Planner and Cisco Feature Navigator to verify critical functionality on required hardware.
